Microzones PSI XPSI

I now have several customers who have Network 8000 controls installed on their site, but have been abandoned by their service provider. Unfortunately, most do not have budgets that allow them to replace the many Microzone 2 controllers or VAV controllers. It has been a couple years since I have connected to the controllers. I had used XPSI or PSI software to direct connect to the Microzones. Is there any other options for connecting to the Microzone 2 controllers? If not, does anyone have the software available to direct connect to Microzone 2 controllers?

MZ's

You have some options. The MZ2 and VAV controllers may not need to be replaced. Do you have the ability to sell them an AX box with the ASD driver? That's a good fix to any front end problems they are having. They probably either had a Host-8000, Signal, or Ultivist front end that died. Are the controllers still working? I would bet they are. You said they have no budget to replace them, but they could put an AX box in and replace any MZ2's that don't work for far less than a complete new system. They have options, they just need to get the right people involved who have experience with those systems. You may want to sub-contract some of it out and then you look like a hero to the customer.

Niagara AX is what we will install at one customers site. The other customer has issues with a MZ2 controlling a RTU right now. My interest right now is to take a look into the MZ2. However, I believe that they too will also need to replace some GCMs at some point in the near future.

I did not get your email, but that is alright. Customer was able to locate PSI and I was able to access controller logic and resolved their current issue. I am certainly interested in getting more info on AX ASD integrations. Thanks for your help anyway.

I can tell you from ekp. that the isoft GCM and ASD drivers both work. The GCM driver is very quick tot setup. Email me/PM if you need any help setting one up, i'd be glad to assist. I could give ya some tips over the phone if your going that route.

Im also in the same position. I ran into a network 8000 controller with MZ controllers connected. There is no computer hooked up to the GCM but there is a keypad and screen on the front of it. No matter what buttons I pushed I couldn't do anything. Im convinced that the problem I ran into is just a setpoint adjustment. There isnt anything too complicated in this building. Its just small apartments with fintube valves and space sensors. Does anyone know how to navigate the front screen on the GCM?

You can hook into a gcm by pluging a modem cable into the left side, the. Plugging it into your computers serial port. Open up hyper terminal or putty set baud to 9600. 8 data bits no parity 1 stop bit, will give you access to the gcms terminal if the one on front is dead
